“Senate GOP campaign arm stole donor data from House Republican”

Staffers for Senate Republicans’ campaign arm seized information on more than 200,000 donors from the House GOP campaign committee over several months this year by breaking into its computer system, three sources with knowledge of the breach told POLITICO.

The unauthorized raid on the National Republican Congressional Committee’s data created a behind-the-scenes rift with the National Republican Senatorial Committee, according to the sources, who described NRCC officials as furious. It comes at a time when House Republicans are focused on preparing to defend their 24-seat majority in the 2018 midterm elections. And it has spotlighted Senate Republicans’ deep fundraising struggles this year, with the NRSC spending more than it raised for four months in a row.
